About

As a Mobile Developer, I bring comprehensive experience, working on a variety of projects, from those aimed at large corporations to those serving a vast user base. My role was crucial in the complete refactoring of an application made with webview framework with over 300k downloads to Flutter, keeping all users connected and ensuring the full functionality of the previous app. I excel in applying advanced programming practices and adopting robust concepts and architectures, including SOLID, code refactoring, clean code, clean architecture, and MVVM. Additionally, I have extensive experience in crafting tests - unit, component, and integration tests - a skill that was the main focus of my final project for my bachelor's degree in Computer Engineering. Beyond technical skills, I have significant experience with various agile methodologies, teamwork, and a strong foundation in the commercial and negotiation area, which have allowed me to develop communication and public speaking skills, essential for success in dynamic and collaborative environments.
